Code | Description |
---|---|

−20337 | The specified time stamp occurs after the end of the limit. |

−20336 | The values of the X array that are contained in the Limit Specification cluster are not monotonically increasing. |

−20335 | Waveforms are not contiguous. You can concatenate two waveforms (A, B) with same dt only if they are contiguous, that is if t0_B = t0_A + N * dt, where N is the number of samples of waveform A. |

−20334 | Cannot align waveforms because their time stamps are separated by more than 10 times the duration of the longest waveform. |

−20333 | Cannot align two waveforms with same dt if their samples are not clocked in-phase. Alignment of two waveforms is possible only if the samples share the same dt and are in-phase, that is the difference between their t0s is a integer multiple of dt. |

−20332 | Internal error: The number of threads attribute is less than zero. If the problem persists, contact National Instruments technical support. |

−20331 | Internal error: The parameter struct pointer is Null, possibly because of changes to the calling VI block diagram. If the problem persists, contact National Instruments technical support. |

−20330 | Internal error: The result pointer is Null, possibly because of changes to the calling VI block diagram. If the problem persists, contact National Instruments technical support. |
